i found that some DNS mismatching while trying to add AD. but that dns is
not listed anywhere
that is showing under krb5kdc.log. CLIENT_NOT_FOUND error message, with
some IP address.
let me try to re-install everything.
which is the suggested Best software version combination ?
Redhat 7 + IPA 3.3 , Redhat 7 + IPA 4.1 or Redhat6.6 + IPA 4.1
